Default blown 383 costs

I finally got the motor back and here is the final breakdown on costs:

Block machining w/hone deck $300.00
Valve job $110.00
Pressure test heads $ 0.00
Cylinder head resurfacing $ 70.00
SCAT/Probe Forged Rotating assembly $1389.00
Upgrade to 4340 steel crank $250.00
Upgrade to 4340 H beams $120.00
Assemble long block $450.00
Complete balance $125.00
Stroker clearance $ 45.00
Canton 15-242T Pan $283.00
Oil pan pick up $ 34.00
Cut dual key on crankshaft + machine front timing cover for BB hub $100.00
Splayed caps + machine work for conversion $275.00
Stroker clearance $45.00
Gasket set $121.00
ARP head studs & main studs $171.00
Melling oil pump $ 0.00
Crane lifters $155.36

Total labor: $1475.00
Total parts: $2523.36
Total + 8.25% sales tax = $4,206.54

Does that sound like a fair price for a fully forged 383 with the 4 bolt splayed main cap conversion?

The assembly and kit sound a bit high...but if you had them purchase it, or just bought a kit, then your going to pay more. You could have saved about 500 on the rotating assembly if you had peiced it together yourself from different suppliers. Other then that looks great for a VERY solid motor.

I forgot that the price included CC 977 springs & seats, Speed Pro Hell Fire rings, clevite bearings, & melling oil pump. They also spent time clearancing the oil pan to clear the dipstick tube....so that almost totals $500.00.

How much power and boost do you think the motor can handle?

Well the car has the above set of upgrades on the motor and in addition to a set of LE2 heads, a ATI D1 Procharger, a custom Brett Bauer/Lloyd Elliot cam, and finally a FMIC.
